Drain Valve 1/4in NPT

The Drain Valve 1/4in NPT from DEWITTS RADIATOR is a precision petcock engineered for efficient coolant drainage in automotive cooling systems. This compact brass drain valve is essential for routine maintenance, system flushing, and complete radiator servicing. Whether you're performing seasonal coolant changes or conducting comprehensive engine cooling system work, this petcock provides reliable access to drain coolant quickly and safely without removing the entire radiator assembly.

Manufactured in durable brass construction, the Drain Valve 1/4in NPT features a 1/4-inch National Pipe Thread (NPT) connection that ensures a secure, leak-free fit to standard cooling system ports. Brass material provides superior corrosion resistance in the harsh chemical environment of coolant systems while maintaining excellent thermal stability. The valve's compact design—measuring 1.35 x 0.75 x 3.1 inches—allows for installation in tight engine bay spaces where larger drain plugs would prove impractical. The straightforward petcock mechanism delivers dependable on-demand flow control without complex mechanisms.

This drain valve is ideal for professional technicians, restoration specialists, and serious enthusiasts who demand OEM-quality cooling system components. It integrates seamlessly with DEWITTS RADIATOR systems and most standard cooling configurations using 1/4in NPT ports. Installation requires only hand-tightening into the radiator's drain port; ensure the engine is cool and system pressure is fully relieved before opening to prevent coolant spray and burns. The lightweight construction (0.06 lbs) adds negligible weight while providing years of reliable service across multiple maintenance cycles.
